Be it lnownvthat I, FREDRICKJ. a citizen of the United States of America, residing ati Philadelphia, i in 1 Philadelphia i 5 county, in the State of Pennsylvania,hav`e .invented a newand useful Apparatus 'for "Use with'llilemmingAttachments for Sewimg MaChinegyV 1" l n l `My invention relatesto apparatus for use with hemming attachments `for sewing It further; [-includes asl anintegralpart of the slide, afslotted ar or`slide, for regulating and adjusting the Awidth of the hem to be made-f- "f W Theobjects of my'iinprovement are:

which opens and closes.

l" i1; To provide` a "hemming attachment f2; Toprovidefacilities whereby, in 'a `hemf ming `attachment forA sewing machines, the

` ,30 lapparatusfor hemming,n`ow in commonuse,

4may' be 'spread or'opened, to admit of` th insertion or removal of fabrics.` i A To.` provide facilities whereby fabrics y '.the slot,\to themovable member of the hempartly` manufactured into *their i intended form maybe inserted in, hemmedby. the

aid of thehemming apparatus and removed,

after being hemmed. d d a i lZ1. To providean apparatus whereby fabrics may be inserted in, hemmed and r'ee0 moved from the hemming apparatus, now in common use, with greater speed and facility than is now possible.

The objects of the invention are attained by the mechanism illustratedin the accompanying drawing, in which: l

Figure 1 is a side view of the apparatus; Fig. 2 is a top view of the apparatus, in detail;

Fig. 3 is a longitudinal cross section of the apparatus. d

The members 4 and 5, shown in the drawing, do not constitute a part of the invention as claimed. They serve to fold the fabric to be hemmed, and to regulate and keep uniform the width of the hem, to be made. They are now in common use, but Without Rosenau,-

the apparatus hereinafter described;` ,These l` members are hereinafter referred to asthe helnming attachment. l t The framework of the apparatus 1, l1 consists Vofthreenpieces of 1netal,.one .forming l a'bed orirest, and the other two placed upon 1' the lowerpiece,parallel to eachother, the

spacebetweenthem forming a groove. *The frame .so formed ispheld together by the rivets 11,11 which joinA theupper pieces to the lower piece. uIt is further supported by thelbracesfland 15,*which'` eXtend across from one of the-upper pieces of the frame to the other. These braces rest upon the upper pieces ofnietahfand are connectedtol them by thebolts 16, 16 which pass through 1;.

' the braces andthetwo thicknesses oflmetal.

A In the groove of the frame, as abovedescribed, the slide. 2, 2, rests. This slide-is lmade `upof two partsor sections. l. Oneof these sections, hereinafterlcalled the llupper,

rests uponthe cushion 13, (Fig. `3)` `which lis attached "to the `other section` of the slide, `hereinaftercalled the lower. In the upper `section of the slide, in that part of it which is adj acentlto the cushion, is a slot," 6. Passw,

sectionof the slide may bel moved back and .l

forth, upon the cushion. The upper section ofthe slide is attached, lat the end opposite ming-attachment, 5.` lThecushion 13, further serves` to bring the upper section ofthe, slide out of the groove, to a level above the sidesformed bythe two upperpieces` of` the frame, as hereinbefore described.

The lower section of the slide is attached, at theend opposite the cushion, to the pivoted lever 3, 3 by the bolt 10. A tension spring 9, is attached to the lever 3, by the same bolt, 10. The other end of the spring `at which the` lever 3 is attached, the fixed section of the hemlning attachment, 4, is attached. To insure rigidity of this section it is attached to both the bed and to the up# per ofthe frame, as shown in Figs. 1

and 3.

The frame ofrthe' apparatus V1, 1 is' 'at-- tached tothe sewing machine, in proper pof sition,"by"bolts secured'in the sewing machine, through the holes 12, 12.

" '"By'mo'ving 'theupp'er section of the slide which thematerial to be-hemmedis. inserted f into the hemming apparatus,' in the space between members )sland- 5. Y The' lever, 3, is then Ymoved into the position :indicated by vvthe' dotted lines. The effect of this is to draw 'fthe slide 2, 2 forward, .and "hence with it, 'the member 5. `This member, 5, is so brought into juxtaposition with member 1, the fabric to be hemmed being carried with it,and into Y rvtheproper positionfor hemming. The lever 7 opies of this .patent may be obtainedV for Vis held in the position into which it has been moved bythe tension of the spring, Vand the exact position is determinedby the pin, 17.

A`riedon, the fabric beingmoved forward, by the! operator, asit is sewn. .It cannot be pulled outfrom the side;v 'When the hemfining operation has been completed the apparatus is opened, by. bringing the lever into p rvthe original position, and the 'material' can 1 VA1.

2. In a hemming attachment lfor sewing machines a slide or bar, divided into two parts or sections, the upper part of the slide or bar, in which is cut a slot, resting upon a cushion, attached 'to the lower section of the slide or bar, and a thumb screw, within the slot, and inserted into the cushion; the lower section of the slide or bar attached to a pivoted lever, and a tension spring attached to thepivoted lever.
